Patent DE-2508524-A1 (DE)
Title: Permanent magnet system for connecting wall elements - is held on matching edge profiles and actuated by rotation
IPC: E05C19/16
Filed: 1975-02-27
Abstract: The door or wall has connecting profiles which can be connected by magnets on adjacent surfaces. This arrangement is used as a partition wall made from a number of travelling wall elements. The separation of the elements joined to form a door or a wall is relatively simple and easy. The adjacent permanent magnets (13, 14) arranged in pairs are rotated for pole changing when the edge profiles (11, 12) are to be separated. Both of these magnets can be rotated for this purpose or only one while the other one remains stationary. These magnets which have circular or square shape are distributed over the edge profile for holding purposes. On pole changing the repulsive force generated assists in separation of door or wall elements.

Title: Floating swimming pool or liquid container cover - which moves with currents to lifting appts. for removal
Inventor: BENZLER HARTWIG DIPL ING DR IN
IPC: E04H4/08
Filed: 1975-03-27
Abstract: The apparatus is for covering and uncovering a swimming-pool or other similar size liquid containers in order to keep the contents clean and to ensure heat insulation. It consists of a cover made out of individual elements placed side by side, the whole cover floating on the surface of the water. A lifting device raises the elements out of the water, singly or in groups, and also replaces them on the surface of the water. In addition, a mechanism which produces water currents causes the elements to move within reach of the lifting device when the water is being uncovered and moves them out of the way of the device once they have been replaced in the water.

Title: Double-pane porthole for ship - window has elastic sealing-ring between panes, buckling outwards when compressed
Inventor: REDLINGER WERNER
IPC: B63B19/02
Filed: 1975-03-29
Abstract: The window is suitable for use in ships, and incorporates two or more parallel panes of equal size, connected to each other by a screw passing through them. The distance between them is varied by means of adjusting nuts. They may be in balls-eye form, with one thicker and more rigid than the other. Between the edges of the panes (2) there is an elastic sealing ring (3), with a cross-section, designed so that its centre part is arched outwards as soon as its ends, which fit against the pane edges, are compressed towards each other. The end parts of the cross-section shape of the sealing ring may engage in grooves (4) in the edges of the panes. A wider gap between frame and panes is permissiblelikewise greater dimensional tolerances, while effective sealing is maintained, without any significant elastic deformation of the panes in the closed position.

Title: Closing unit for injection moulds with core inserters - has fitting collars on cores locating in recesses
Inventor: HUEBERS ERNST
IPC: B29C33/20
Filed: 1975-07-02
Abstract: The parent patent described a clamping unit for moulding highly reactive molten masses of resin i a highly fluid state, in moulds heated to a temp. higher than that of the melt. The mould halves were closed first and the cores were inserted afterwards; the resin being allowed to consolidate, after the mould was filled, under relatively low press. In this addn. the closing unit has a frame supporting a mould divided in a plane in the direction of which, the mould halves open and close normally; one or more cores being inserted. The core is provided ith an accurately dimensioned collar, whilst the mould halves have a corresp. counterbore, positioned so that when the mould halves are closed, after the cores (102,104) have been inserted, the collar (114) positively and accurately aligns the mould. The arrangement not only ensures accurate guiding and positioning of the mould halves, so as to give more accurate mouldings, but also prevents vibration and overloading of the tools and the moulding when the press is opened.

Title: Soil sample core tube closure - has leaf spring acting on flexible hose piece fixed at bottom end
Inventor: PIELES NORBERT DR
IPC: E21B25/06
Filed: 1975-10-22
Abstract: The soil sampler tube consists of a core tube with a cutting edge which can be rammed into the soil to be sampled. A flexible piece of hose is fixed with its lower end to the core tube. The upper end is attached with the free end of a leaf spring so that the core sample is securely trapped when the sampler tube is withdrawn. This does not obstruct the passage for an entering core and does not therefore hinder the ramming action. The escape of sample cores, even of wet sands, is eliminated. The core tube (1) is threaded at the end for the connection of a cutting shoe (4). A conical ring (3) is used to fix a flexible piece of hose (2) to the bottom end. A leaf spring (5) is also securely held at the bottom: it fits into a bonded or sewn pocket (6).

Title: Ceramic tile colour patterning press - has metal partitioning strips forming stencil for separate colour applications
IPC: B28B13/02
Filed: 1975-11-11
Abstract: The ceramic tiles are machine-coloured using a stencil formed by thin metal strips as wide as the tile is thick. The strips are set on edge in a frame, and the spaces between them define the various coloured areas. At the first station, all the areas which are not to recieve the first colour are covered with a blanking plate, and the first colour is spread in the spaces left open. A second colour is added in similar fashion in a second set of areas. Finally the remaining areas are filled with the ground colour. The stencil is then lifter out and the tile consolidated in a press. The method of application gives a wider choice of decoration than the inexpensive method at preset in use.

Title: Bonded wood dust-burning furnace - eliminates gaseous toxic components by direct combustion without scrubbing of flue gases
Inventor: JODEIT UDO DIPL ING
IPC: F23G7/10
Filed: 1976-11-18
Abstract: The firing plant is used for non-toxic firing of bonding agent containing dust generated by wood grinding. This dust is generated on grinding the surfaces of the composite wood chip panels during their manufacturing process. The toxic components in the combustion gases such as formaldehyde and phenol are completely eliminated by combustion and no additional gas scrubbers are needed. The toxic gases are burnt directly at the location where they are formed in the process. The necessary combustion chamber temperature for ensuring elimination of toxic components can be selected independently of the heat demands of the downstream connected thermal processes such as drying of the wood chip used in the manufacture. An air preheater is arranged upstream of the combustion chamber so that the combustion air is preheated by the combustion gases and the flue gases are cooled by combustion air.
